The Impacts of Age-Related Peripheral Hearing Loss, Central Auditory Processing, and Cognition on Quality of Life in Older Adults: A Scoping Review

This scoping review aims to synthesize peer-reviewed literature exploring quality of life (QoL) for individuals with age-related hearing loss (ARHL), age-related central auditory processing (ARCAP) deficits, and age-related cognitive decline. A growing body of research has identified ARHL as a risk factor for the development of dementia, highlighting the connection between the sensory and cognitive systems. As the aging population continues to grow, examining comorbid age-related hearing and cognitive decline is especially relevant. These conditions may have potential negative consequences on the daily functioning, social participation, mental health, and overall wellbeing of older adults. A systematic search of peer-reviewed literature was conducted across multiple databases, adhering to the PRISMA guidelines for scoping reviews. Studies that focused on the impact of ARHL, ARCAP deficits, and/or related cognitive deficits on QoL were included in the present review. Key data extracted included QoL measures categorized into the ICF framework, the effects of hearing loss intervention on QoL, and the impact of ARHL on QoL for aging individuals. This review summarizes the reported effects that ARHL, ARCAP, and/or cognitive decline have on older adults, and discusses the clinical and practical implications for managing clients with these conditions. In addition to preventative measures and deficit management, maintenance of life participation, social engagement, and overall wellbeing should be considered when caring for aging adults with hearing and/or cognitive impairment.
